HEDDLE FRAME.

Application flied February To allwhomitma concern:

Be it known t at I, JAooB' KAUFMANN, a citizen of the United States,residing at Elkins Park, in the county of Montgomery 6 and State ofPennsylvanla, have invented certain new and useful Improvements inHeddle Frames, of which the following 1s a specification.

My invention relates to heddle frames for looms, and it has particularrelation to means for supporting the heddle bars intermediate theirends.

The principal object of my invention is to provide improved means forsupporting 1 the heddle bars intermediate their ends which will securelysupport said bars against undesirable motion, but which. however, willpermit the bars to be conveniently mounted in and dismounted from theframe when desired.

My present invention contemplate/s an imroved device for supporting theheddle are intermediate their ends which, while permitting the bars tobe more easily and 26 conveniently inserted and removed than heretofore,is so constructed and arranged as to reduce to a minimum the likelihoodof the supporting device becoming disarranged while the heddle frame isin use and thereby fouling with the adjacent frames in the loom, thusminimizing the possibility of damage which might be occasioned by suchdisarrangement.

The nature and characteristic features of 85 my present invention willbe more readily understood from the following description, taken inconnection with the accompanying drawings forming part hereof, in which:

Figure 1 is an elevational view of a heddle 4 frame provided with heddlebar supporting devices embodying the main features of my presentinvention;

Fig. 2 is a fragmentary sectional view, enlarged, taken approximately.on the line 2-2 of Fig. 1, the parts being shown in the normalpositions assumed while supporting the heddle bar in the frame;

Fig. 3 is a similar view, but With the parts in the open position forthe purpose of removing or mounting the heddle bar therein; and

device mounted on the heddleframe with the heddle supporting bar inoperative relation thereto. I

Referring to the drawings, the heddle frame there shown consists of thetop and bottom bars 6 connected at their ends by means of the sidestrips 7 Extending from end to end of the heddle frame, and arrangednear the top and bottom bars 6 in the usual manner, are the heddle bars8, upon which the heddles 9 are mounted.

The inner edge of each of the heddle frame bars 6 is preferablyrecessed, as at 10, wherever it Is desired-to support the heddle barsintermediate their ends. In this recess 10 is mounted the base portion11 of a bracket member constituting a, part of the supporting device.The bracket member also has a portion 12 extending at right angles tothe base portion 11, and consequently at right angles to thelongitudinal extension of the heddle bar 8. In the extending portion 12of the bracket member there is provided a recess 13 open at one side, asclearly shown in Fig. 3 of the drawings, for the reception of the heddlebar 8.

A plate member 14 is pivoted to the extension 12 of the bracket member,preferably by means of a rivet 15, this pivotal connection being locatedat a point beyond the location of the recess 13. The pivoted platemember 14 is also provided with a recess 16, open on the side oppositethat upon which the recess 13 of the extension 12 of the bracket memberis open, the arrangement being such that when the plate member is in itsclosed position, as shown in Fig. 2 of the drawings, the heddlesupporting bar will be limited against sidewise movement, as well as upand down movement, in the coacting recesses 13 and 16. The end of theplate member 14, remote from the ivot 15, is also recessed as at 17 asclearly shown in Fig. 3 of the drawings. A plate spring 18 is secured tothe base portion 11 of the bracket member by means of the screws 19,which also serve to secure the base portion 11 of the bracket member inposition. The free end 20 of the plate spring 18 extends through anaperture 21 in the bracket member, located at the juncture of theextending portion 12 and the base portion 11 of said bracket memher. Theplate spring is adapted, when the parts are in their normal operativepos tion, as illustrated in Fig. 2 of the drawings, to act as a latch byengagin the recess 17 of the plate member 14 an thereby securely lockingthe same in the closed position for su portingthe heddle bar 8. It willbe note however, that the free end 20 of said leaf spring 18 maymanually operated to free the same from its engagement with the recess17, and thereby permit the member 14 to be swung to the open positionwhen desired. The end of the plate member 14 has a curved inclinedportlon 22 adjacent the recess 17, so that the plate member may besnapped into the closed position, without necessitating the raising ofthe end of the leaf spring 20, when 1t 1s desired to close the platemember 14 over the heddle bar 8.

The operation of the device will now be quite apparent. The supportingdevices being mounted in the heddleframe, as hereinbefore set forth, andit being desirable to mount a heddle supporting bar in the frame in suchmanner that the same'will be supported therein intermediate its ends,the heddle bar, with the heddles mounted thereon, is placed in the framein the usual manner and its ends secured in position by means ofwhatever type of fastening device that may be used in connectiontherewith, the pivoted member 14 being in the open position as shown inFig. 3 of the drawings. The central portion of the heddle bar is nowinserted in the recess 13 of the extension 12 of the bracket member,and-thereafter the pivoted member 14 is swung into the position shown inFig. 2 of the drawings, permitting the latch-like end of the leaf spring18 to engage the recess 17 intheend of said pivoted member 14. Themember 14 will now be securedly held in the closed position, confiningthe heddle supporting bar within the recess 13 of the extension 12 of.the bracket member. when it is desired to remove the heddlesupporting-bar 8 from the supporting device, it will be necessary tomanually lift the free 'end 20 of the leaf spring 18 from out ofengagement with the recess 17 of the pivoted plate member 14, whereuponsaid plate member 14 may be swung to the open position to thereby permitthe heddle supporting bar to be removed.

It will be seen that there is thus provided a simple yet efiicient meansfor supporting the heddle bars intermediate their ends which willprevent undue lateral movement of the heddle bars, and which is also soconstructed and arranged as to prevent disarrangement of the parts ofthe supportmg device itself. Possibility of the parts of the heddleframe, as well as of the supporting device itself, fouling on adjacentframes, during the reciprocation of the frames 111 the loom, willthereby be reduced to a min? imum.
